The day across the three live Derivasys markets.
Compared with October 4 at 16:29 UTC, Bitcoin's 1W ATM IV rose 0.35 volatility points, whereas Ether's 1W ATM IV fell 1.02 volatility points and Solana's 1W ATM IV fell 1.53 volatility points. These divergent changes narrowed the Solana-versus-Bitcoin 1W ATM IV level dispersion by 1.88 volatility points to 17.79 volatility points, from 19.67 volatility points.
What is unusual today?
One-week ATM IV level dispersion: Compression: 17.79 vol points; signed spread change -1.88 vol points. Historical percentile rank 34%. Stored one-week tenor comparison at this cutoff across 3 assets. 32 historical observations; minimum 20.
Daily one-week ATM IV-change dispersion: The cross-asset spread is 1.88 vol points. Historical percentile rank 25%. Stored daily changes across 3 assets. 32 historical observations; minimum 20.
BTC stands apart: 1W ATM IV change is 1.37 vol points above the group median. Stored cross-section of 3 assets at this report cutoff.
This is a comparison, not a pooled surface: each asset keeps its own forwards, expiries, SVI fit and realised-volatility history.
Cross-sectional thesis
Where the complex is diverging.
One-week ATM IV level dispersion is compressing, at 17.79 vol pts; daily one-week ATM IV changes span 1.88 vol pts across the complex.
ETH has the highest 1W IV-minus-7D-RV spread at +3.00 vol points; SOL has the lowest at -1.17 vol points. The range between these spreads is 4.17 vol points.
Aligned 24-hour spot correlations: BTC/ETH 0.87 (25 observations).
Historical cross-sectional readings: 1W ATM IV level dispersion percentile rank 34.4%; Daily 1W ATM IV-change dispersion percentile rank 25.0%; 1W RR25 dispersion percentile rank 37.5%; IV-minus-realised dispersion percentile rank 72.0%.

Macro and crypto context
5 October 2026
Crypto: The Block reported that Strive added 2,000 bitcoin, with holdings nearing 30,000 BTC. CoinDesk separately reported that Ethereum investors faced a two-week staking exit line. These provisional single-source reports add treasury and staking context, but neither establishes a cause for the Ether-versus-Solana volatility comparison or the divergent daily 1W ATM IV changes.
Completed-session cross-asset context
Crypto volatility against VIX and SPX.
The benchmark comparison is separately timestamped to the latest completed US session; it does not replace the intraday crypto surface cutoffs above.
BTC and ETH and SOL 30-day implied volatility remained 2.2–3.5 times VIX, while short-window equity correlations remained mixed.
| Asset | 30d ATM IV | VIX spread | IV / VIX | 20d crypto RV | 20-session SPX RV | RV spread percentile | 30-session correlation |

Original report summary
Ether (ETH) and Solana (SOL) defined the 1W IV minus 7D realised volatility dispersion of 4.17 volatility points at the October 5, 16:29 UTC cutoff. Ether had the highest spread and Solana the lowest when comparing one-week ATM implied volatility with seven-day realised volatility. Bitcoin stood between them, while daily changes compressed the outright 1W ATM IV range.

}06 · Methodology and provenance
A derived publication with no duplicated market data.
The report is assembled at request time from the immutable BTC, ETH and SOL daily-report artifacts for the same UTC report date. It is omitted unless all three exist. Cross-asset averages are descriptive and equal-weighted; no attempt is made to combine distinct volatility surfaces into a single fit.
